Definitions

  • the present invention relates to wireless communication systems such as Public Mobile Radio (PMR) and Cellular Telephone systems as well as wireless notification or paging systems and satellite communications systems and to methods of operation thereof.
  • PMR Public Mobile Radio
  • paging is used when the network needs to contact a user terminal (UE) which is not currently communicating with the network or cannot communicate with the network - e.g. in a system using pagers having no communication possibility.
  • UE user terminal
  • a UE is paged when it has gone into a mode where it uses discontinuous reception.
  • the objective of paging is typically to contact the UE and to transfer a message.
  • the message may include an implicit or explicit request for the UE to contact the network by sending a random access request on an access channel. In this way, communications can be set up between a mobile UE and the network.
  • Paging can be used towards individual UE's or to groups of UE's, typically as a notification channel in case of activity on a group call.
  • paging is based on addressing, for example, a group address, a fleet address, an individual address, a set of individual addresses or addresses within a certain range or address segment. Either temporary of permanent addresses can be used.
  • the purpose of the paging is also indicated to the terminal e.g. for a mobile UE terminated phone call, a mobile terminated Short Message (SMS), an alphanumeric message to be displayed on a pager.
  • SMS Short Message
  • Positioning or location techniques based on radio signal measurements in support of Location based services are known for wireless cellular telecommunications systems, for example from the standard 3G TS 25.305 version 3.1.0 release 1999 "Functional Specification of Location Services”.
  • a general description of location services and the service requirements is given in the specification 3G TS 22.071.
  • Locating the UE involves two main steps:
  • the signal measurements may be made by the UE, a base station or a dedicated location measuring unit (LMU).
  • the basic signals measured are typically radio transmissions, but some optional methods may make use of other transmissions such as general radio navigation signals.
  • the location estimate computation may be made in the UE or by a calculation function located in the network.
  • the location information may be requested by and reported to a client (application) associated with the UE, or by a client within or attached to the network.
  • the location information may also be utilised internally within the network, for example, for location assisted handover or to support other features such as home location billing. There are many different possible uses for the location information.
  • the location feature may be used internally by the network (or attached networks), by value-added network services, by the UE itself or through the network, and by "third party” services.
  • the feature may also be used by an emergency service (which may be mandated or "value-added”), but the location service is not exclusively for emergencies.
  • Positioning or location techniques have also been envisaged as a trigger to handovers, and also as means to support network planning i.e. having the UE report means to determine its position along with radio measurements so that the quality of reception can be logged by the network for each position of the mobile.
  • a geographical area for a wireless cellular communications system is generally divided into separate radio coverage areas or cells.
  • a base station is located in each cell and a mobile user equipment (UE) communicates with one or more base station transceivers located in one or more cells during an active call.
  • UE mobile user equipment
  • a location area is not known precisely. If a UE leaves a location area it will normally register itself with the new location area via the cell in which it is currently located (Location Updating).
  • Both location areas and base stations generally have an identifier (LAI, Location Area Identifier and BSI, Base Station Identifier) which are generally transmitted on a common signalling channel). Except under special circumstances, the network does not know the position of the UE any more accurately than this. Hence, if the network wishes to make contact with the UE it generally sends a paging request on a suitable (usually common) signalling channel starting with the cells of the last location area in which the relevant UE registered.
  • Location updating causes updating of subscriber data of the UE in question in the subscriber database, typically in a VLR, Visitor Location Register associated with a Mobile Exchange (MSC).
  • MSC Visitor Location Register associated with a Mobile Exchange
  • location area is made smaller, the amount of signalling increases as UE's move from one location area to the next at a higher frequency. For this reason location areas are typically rather large, usually several cells in size. Such a large size does not allow services to be provided which depend upon paging UE's in smaller areas, say 200 to 2000 meters in diameter.
  • a cellular radio system comprising a multitude of base stations for offering a radio interface to mobile terminals.
  • the radio interface is used for communicating general information to the mobile terminals and arranging for dedicated communication between a certain mobile terminal and the cellular radio system.
  • the system comprises a certain first base station arranged to transmit, similarly to said general information, information about the nature of the restrictions applicable on said area to the mobile stations.
  • a mobile terminal receives a paging call signal including call identification information defining identification conditions and when at least one piece of reference identification information thereof fulfils the identification conditions, the mobile terminal identifies that the received paging call signal is a call signal intended for the same.
  • the at least one piece of reference identification information includes variable identification information.
  • the mobile terminal receives GPS signals to determine the position of the same for changing the variable identification information based on a result of the determination of the position thereof.
  • a mobile communications system using the mobile terminal is also provided.
  • WO0030379 describes a system in which the originator of a message specifies a target area of reception.
  • the target area of reception is compared to location data usually representing the terminal location.
  • location data is determined by a positioning receiver and loaded into a register.
  • the location data is loaded into the register by manual keypad entry or by transmission over the network, so that the location data can define a location of interest other than the terminal's current geographic location, or so that terminal location data can be provided for communication terminals that lack a positioning receiver.
  • the present invention has as an object, the provision of a system and method for organising a wireless communications system which allows notifications of a single user equipment or a group of user equipments within a specified geographical area.
  • a further object of the present invention is the provision of a system and method for organising a wireless communications system which allows notification of a group of user equipments within a specified geographical area which can be selectable in size without having to store and update the locations of the mobile UE's within the area.
  • a further object of the present invention is the provision of a system and method for organising a wireless communications system which allows a user to decide on whether the location of the user equipment is made known to the network.
  • the present invention provides a wireless telecommunications network comprising at least one base station transmitter and a plurality of user equipments able to receive radio messages from the at least one base station transmitter, the network being adapted to transmit a paging message to at least a sub-group of the user equipments and a user equipment in response to the paging message being adapted to transmit an access request to the telecommunications network, characterised by means for determining the present location of a user equipment, the paging message comprising a representation from which the user equipment can determine whether its present location is within a defined geographical area, and each user equipment which determines that its present location is within the defined geographical area being adapted to carry out, in response to the determination, at least one operation selected from a group of operations, one operation of the group being the transmission of the access request to the telecommunications network.
  • the present invention provides a method of operating a wireless telecommunications network comprising at least one base station transmitter and a plurality of user equipments able to receive radio messages from the at least one base station transmitter, the method being characterised by:
  • the present invention also includes a mobile user equipment for use with a wireless telecommunications network comprising at least one base station transmitter, the user equipment comprising: an antenna for receiving a paging message from the base station transmitter; means for determining the present location of the user equipment and means for determining whether the present location of the user equipment is within a defined geographical area; and means to transmit an access request to the wireless telecommunications network, characterised by the paging message including a representation from which the user equipment can determine whether its present location is within the defined geographical area, and the means to transmit an access request to the wireless telecommunications network is adapted to transmit the request in response to the determination.
  • the present invention also provides a method of operating a mobile user equipment for use with a wireless telecommunications network comprising at least one base station transmitter, the method being characterised by:
  • a transmitter for use with the present invention may be a base station transmitter used for conventional voice and data transmissions to user equipment. It may however, also be an independent transmitter which is specially used for transmitting notification messages according to the present invention.
  • the representations included in the notification message are preferably time differences between transmissions from pairs of base stations of the system. Preferably, three time differences are included in the notification message thus providing a form of triangulation from which a user equipment can decide whether it is a defined geographical location without excessive computational effort.
  • the present invention may be applied to wireless communication systems such as Public Mobile Radio (PMR) and Cellular Telephone systems as well as wireless paging systems and satellite communications systems and to methods of operation thereof.
  • a pager generally has a pager receiver, an alphanumeric and/or audio and/or other visual display as well as an internal memory and a computing device such as a microprocessor.
  • a cellular wireless system suitable for use with the present invention may be exemplified by the following non-limiting list: AMPS, IS95, GSM (Global System for Mobile Communications), NMT (Nordic Mobile Telephone), UMTS (Universal Mobile Telecommunication System) and any other system as described for instance in "Wideband CDMA for Third Generation Mobile Communications", Ojanperä and Prasad, Artech house, 1998.
  • Satellite systems are described for instance in "Satellite Communications Systems", G. Maral and M. Bousquet, Wiley, 1998.
  • the present invention will mainly be described with reference to a cellular wireless communications system but the present invention is not limited thereto but only by the claims.
  • a method and related equipment is provided so that the network can notify all UE's or a sub-group of UE's based on their position (e.g. to notify all UE's within a certain area, this area not necessarily being the same area as a location area and preferably being a smaller area such as an area of less than 2,000-5,000 meters diameter) without having to store location details of a large number of UE's, e.g. without having to continuously store precise location details of all UE's.
  • the UE's may be located in one or more cells. The UE may have complete control over whether its position is made known to the network.
  • An embodiment of the present invention includes the following method steps:
  • Implicit in this method is the ability of the UE to determine its own position with reasonable accuracy. It may do this via an on-board GPS receiver or the network may assist in the self-location of the UE. Once, contacted, the network can then obtain from the user terminal a number of different types of information, such as signal strength received by the user terminal, reports of time differences between transmissions from different base stations, reports on synchronisation or other network information.
  • One preferred addressing method for notification is to use an address where every UE has to decode the associated paging channel.
  • a structure of the paging channel could also be defined so that all UE's, whatever their paging group, are made aware that such a group paging has been made e.g. one bit on all paging messages could indicate that all terminals have to read a full cycle of paging messages.
  • a specific group paging address can also be associated with a given service e.g. paging addresses address certain service capabilities instead of a UE address.
  • the notification message can be tagged in accordance with a specific service as well as containing geographical reference information.
  • a specific paging reference or address can be allocated to a feature such as paging on location co-ordinates in accordance with the present invention. All UE's supporting such a feature would then be capable of recognising that reference or address and of decoding the contents of the paging message from which they can obtain the geographic data necessary to determine if the message is one relevant to that UE.
  • the paging message contains means to identify a geographical location, either a point location or an area.
  • a geographical area which includes a shopping mall.
  • Information relevant to that shopping mall may be selectively sent only to mobile terminals within the geographical area of the shopping mall.
  • An advantageous means to identify a geographical area is a list of time intervals, e.g. propagation time delays or relative propagation time delays to identified base stations.
  • the paging message would then include a set of time delays and a set of associated base stations (e.g. defined by base station identifiers). Where all the paged UE's are in one cell, one time interval may be representative of the relative propagation time difference to the base station of the current cell. Other time signals could be representative of propagation delays associated with a neighbouring cell or cells with which the UE can make radio signal measurements.
  • a number of such delays from different base stations provides a triangulation system which can identify a point if the plurality of distances from the base stations all coincide at one point, or an area if they do not.
  • a typical number of signal measurements required to provide adequate triangulation is 3 to be enough for a given reliability.
  • a point is defined by the information in the paging message
  • a further distance may also be transmitted in the paging message, this distance defining a radius around the identified point in order to define a geographical area. The UE then compares its position with the identified pint and determines if its location lies within the circle defined by the point and the transmitted distance information as radius of the circle.
  • the above techniques involving latitudes, longitudes and distances can involve complex calculations such as sin, cosine, or square root functions.
  • look-up tables to define values of such functions is imprecise.
  • a preferred embodiment of the present invention only involves comparisons of values and no calculations of trigonometric or complex algebraic functions.
  • This may be achieved by the paging message including a set of time delays or differences as measured with respect to a set of base stations.
  • the paging message may specify a range of time delays or differences which define the required area. This range may be defined by a % of the time delays or time differences, by an absolute tolerance or range of each time delay or difference or by any similar method. By default, a pre-defined % or absolute tolerance may be stored in the UE.
  • a time delay may determine a distance to a base station.
  • a UE may determine the time delay to an identified base station by measuring the round trip time of a message from the UE to the respective base station and back. However, such a measurement requires the mobile terminal to be communicating with the system.
  • An alternative is that the UE has a source of accurate time with which it can compare the arrival time of messages from a base station and from which it can calculate the time differences.
  • Such an accurate clock may be provided by the network for UE's over the air interface or by other radio transmitted clocks.
  • a reference in the notification message to relative transmission time differences between groups a of base stations pairs, i.e. the difference in time taken for a signal to travel from a first base station and a second base station to the UE.
  • the time delay defines the locus of a point along which the specified time difference is true.
  • two or more loci are defined. Their point of intersection then defines the relevant geographical point.
  • the intersection of three such loci is used to define the geographical area.
  • Fig. 1 is a schematic representation of a group of cells of a wireless telecommunications system with a base station transceiver at the centre of each cell.
  • a notification signal is built in the Mobile Exchange MSC and broadcast from the three transmitters T 1 , T 2 , T 3 .
  • the message defines (in a first part of the message) three or more negative tolerances ⁇ TD 12 , ⁇ TD 23 , ⁇ TD 31 and three or more time differences TD 12 , TD 23 , TD 31 , which are the time differences between transmissions from pairs of base stations 1 and 2, 2 and 3 and 3 and 1, respectively. These time differences are defined in certain standards, e.g. they are referred to as "Observed Time Differences" OTD in standard TS 25.305.
  • These representations define regions R 1 , R 2 , R 3 with respect to the relevant transmitting base station pairs T 12 , T 23 , T 31 .
  • a region A is defined.
  • the notification message includes representations from which the UE 1 can deduce whether or not it is in the region A.
  • the loci actually define a figure in three dimensions, a hyperboloid.
  • the hyperboloid must be considered.
  • the geometry of the base station locations may affect the accuracy of the location estimate. The best results are when the base stations equally surround the UE. If they do not, there is a reduction in accuracy, which is sometimes termed the Geometric Dilution of Position (GDP).
  • GDP Geometric Dilution of Position
  • Each UE 1 authorised to decode a first part of the paging message extracts the time difference information TD 12 , TD 23 , TD 31 ; ⁇ TD 12 , ⁇ TD 23 , ⁇ TD 31 and references to the base stations T 1 , T 2 , T 3 and compares actual time difference measurements for these base stations at the UE 1 with the transmitted values. If each measured time difference MTD 12 , MTD 23 , MTD 31 lies within the respective range TD 12 to TD 12 - ⁇ TD 12 ,TD 23 to TD 23 - ⁇ TD 23 , TD 31 to TD 31 - ⁇ TD 31 , the UE 1 assumes it is within the specified geographical region A and decodes the rest of the notification message.
  • TD 1 and TD 2 could be transmitted whereby the difference between the two is the offset.
  • a reference number, code or identification may be included in the notification message. This can be used to distinguish different notification messages with representations of co-ordinates relating to differing geographical areas in one cell.
  • the UE's can reply to the network giving the reference code so that the network can identify which mobile UE's are answering to which notification message.
  • the accuracy of each of these measurements contributes to the overall accuracy of the location estimate.
  • One is to synchronise the transmissions of the base stations.
  • the RTD are known constant values that may be entered in a database and used when making a location estimate.
  • the synchronisation must be done to a level of accuracy of the order of tens of nanoseconds (as 10 nanoseconds uncertainty contributes 3 metres error in the location estimate).
  • Drift and jitter in the synchronisation timing must also be well controlled as these also contribute uncertainty in the location estimate. Synchronisation to this level of accuracy is currently available through satellite based time-transfer techniques.
  • the transmission times may all be aligned to a common reference in which case all RTD have a common value.
  • the transmissions may have a fixed offset with reference to the reference and thus the RTD values are non-zero and may be stored in the database.
  • the location methods do not require the base station network to be synchronized.
  • the base stations may be left to free run within some constraint of maximum frequency error.
  • the RTD will change (slowly) with time. The rate of change will depend on the frequency difference and jitter between base stations. If, for example, the maximum frequency difference between two base stations is ⁇ 10 -9 , then the start of transmission of a 10 millisecond code sequence will drift through a cycle in about 1 390 hours (or 57 days). With this relatively slow rate of drift the RTD can be measured using fixed measuring units at known locations and stored in the database. The jitter and drift of the individual oscillators in each base station may cause the change of timing to slow, remain constant or reverse direction over time. Ongoing measurements of the RTD may be made to assure the most current values are available for the calculation function.
  • the RTD measurement units may be co-located with the base stations or installed at other convenient locations in the coverage area, and report their results through network signalling channels.
  • the RTD used in the calculations for the representations to be included in the notification message should be determined only a short time before the notification message is sent. In order to assure less than a 20 nanosecond uncertainty in the RTD value, the message must be sent within 10 seconds if the maximum frequency difference between the base stations is ⁇ 10 -9 .
  • the notification message in accordance with the present invention may trigger a large number of network accesses within a short time of transmitting the notification message. Such a large number may disturb the operation of the relevant cell or even block its operation for other users.
  • each mobile UE is adapted to delay reply to the notification message by a random time delay. By suitably dimensioning this delay, the access rush can be spread over a reasonable length of time, this avoiding blocking of the cell operation.
  • UE's supporting LCS in Idle mode may run the necessary set of radio signal measurements permanently so as to trigger applications on the internal memory of the UE (e.g. SIM memory) in need of such location information (mobile based positioning). For such UE's, these measurements would suffice.

  • IPDL Idle Period DownLink
  • each base station ceases its transmission for short periods of time (idle periods).
  • idle periods During an idle period of a base station, terminals within the cell can measure other base stations and the hearability problem is reduced. Also, during idle periods real time difference measurements on the base stations can be carried out to determine any offsets or asynchronicity. Because the IPDL method is based on forward link (downlink) the location service can be provided efficiently to a large number of terminals simultaneously.
  • the Idle Periods may be arranged in a predetermined pseudo random fashion according to higher layer parameters. These parameters are used by the transport layer to arrange and use these Idle Periods. Idle Periods continuous mode or burst mode. In continuous mode the Idle Periods are active all the time. In burst mode the Idle Periods are arranged in bursts where each burst contains enough Idle Periods to allow a UE to make sufficient measurements for it to determine if it is in the specified location. The bursts are separated by a period where no Idle Periods occur.
